build.env sets up the Environment:
export DH_VERBOSE=1
export GCC_TARGET=armel
export DEB_CROSS=yes
# this prevents some stupid error making info files
export GFDL_INVARIANT_FREE=no
export with_gomp=no
export biarch32=no

fakeroot debian/rules control

export DEB_CROSS_NO_BIARCH=yes

nb building 'control'g adds build-deps which were not in the normal dsc)
then normal build
